Abstract

A push key device, which includes a base plate, a switch, a bearing plate and a push key. The switch is electrically fixed on the base plate. The switch includes a body and a lever that can slide relative to the body. By sliding the lever, the switch can be turned on or off. The bearing plate is fastened on the base plate, and the bearing plate includes an arched sliding groove and a limiting hole. The limiting hole runs through the bottom of the sliding groove. The push key is located in the sliding groove and can slide along the sliding groove. A shift fork is arranged on the push key at a position corresponding to the shift lever. The shift fork passes through the limiting hole and engages with the shift lever. The push button device of the present invention is respectively provided with a shift fork and a shift rod engaged with each other on the push button and the switch, and converts the arc movement trajectory of the push button on the bearing plate into the linear movement trajectory of the switch lever, and has a simple structure. Strong practicality.

Description

Push key device

Technical field

The present invention relates to a kind of push key device.

Background technology

Push key device is a kind of basic actuation means that is widely used in the various electronic products, as is applied on the control panel of portable electron device.In order to cooperate the small and exquisite day by day trends of design of portable electron device, push key device itself also is asked to possess compact characteristic.

The form of focusing push key device is varied in the digital camera at present, and some is a knob, and some is a slidingtype.Because the focusing push key device is located at the outer surface of digital camera, just must take all factors into consideration the shape and the situation such as position of focusing push key device on digital camera of the shell of digital camera when therefore push key device is focused in design.User's operation for ease now; Some manufacturer designs the top at digital camera with the focusing push button of digital camera; And adopt the slidingtype push button; Loading plate for cover top portion is the digital camera of arch like this, and the slip of focusing push button on the arch loading plate of cover top portion is necessary for the circular motion track, just can guarantee in the process that the focusing push button slides but the driving lever of the switch of control focusing is necessary for straight-line trajectory; The adjusting of digital camera focal length is more even, and the straight-line trajectory that therefore how the circular motion track between push button and the loading plate is converted into the driving lever on the switch has just become urgent problem.

Summary of the invention

In view of this, be necessary to provide a kind of push key device, can the circular motion track of push button be become the straight-line trajectory of the driving lever on the switch.

A kind of push key device, it comprises a substrate, a switch, a loading plate and a push button.Said switch electrically is fixed on the said substrate, and said switch comprises the driving lever that a body and can said relatively body slides, and said driving lever just can be controlled opening or closing of said switch through sliding.Said loading plate be located on the said substrate, and said loading plate comprises the sliding tray and a spacing hole of an arch.The side of said sliding tray is provided with the outer rim of a convexity, and the bottom of said outer rim is formed a groove by hollow out.Said switch is placed in the said groove.Said spacing hole runs through the bottom of said sliding tray and is connected with said groove.Said push button is positioned at said sliding tray, and can slide along said sliding tray.Be provided with a shift fork with the corresponding position of said driving lever on the said push button.Said shift fork passes said spacing hole and said groove and said driving lever and fastens.

Push key device of the present invention is provided with the shift fork and the driving lever of mutual engaging respectively on push button and switch, very easily the circular motion track of push button on loading plate changed into the straight-line trajectory of the driving lever of switch, and is simple in structure, practical.

Fig. 2 is the sketch map of another angle of the push key device of Fig. 1;

Fig. 3 is the constitutional diagram of the push key device of Fig. 1;

Fig. 4 is the cutaway view along the IV-IV line gained of Fig. 3.

Embodiment

To combine accompanying drawing below, the present invention will be done further detailed description.

See also Fig. 1, be the push key device 1 that embodiment of the present invention provides, said push key device 1 comprises substrate 10, one switches, 20, one loading plates 30 and a push button 40.

Said switch 20 electrically is fixed on the said substrate 10.Said switch 20 comprises a body 21 and a driving lever 22.Said driving lever 22 can slide by said relatively body 21.Through stirring said driving lever 22, just can control opening or closing of said switch 20.

Said loading plate 30 be located on the said substrate 10.Said loading plate 30 is domes, and it comprises the sliding tray 31 and a spacing hole 32 of an arch, and the side of said sliding tray 31 is provided with the outer rim 33 of a convexity, and the bottom of said outer rim 33 is formed a groove 34 by hollow out.Said spacing hole 32 runs through the bottom of said sliding tray 31, and is connected with said groove 34.

Said push button 40 is positioned at said sliding tray 31, and can slide along said sliding tray 31.Said push button 40 is domes, and it comprises a key plate 41, one push buttons 42 and a shift fork 43.Said key plate 41 comprises an extrados 41a, an intrados 41b and a side 41c.Said intrados 41b is provided with many reinforcements 44 (see figure 2)s.Said push button 42 is positioned on the said extrados 41a.Said shift fork 43 is fixedly arranged on the said intrados 41b and the driving lever 22 corresponding positions of said switch 20, and level is stretched out said side 41c.Be appreciated that said shift fork 43 also can be along vertically extending away from the direction of intrados 41b, and expose said loading plate 30.

See also Fig. 2 to Fig. 4; During assembling; Said loading plate 30 is placed on the said substrate 10, and this moment, said switch 20 was placed in the said groove 34, and the shift fork 43 with said push button 40 passes said spacing hole 32 then; Engage with said driving lever 22, said push button 40 just can slide along said sliding tray 31.

During use, because the shift fork 43 of said push button 40 and the driving lever 22 of switch 20 fasten, therefore promote said push button 42, when making said push button 40 in sliding tray 31, carry out the arc track motion, the driving lever 22 that just can drive said switch 20 carries out the straight path motion.Thereby said push button 40 is transformed into the linear movement locus of the driving lever 22 on the said switch 20 at the circular motion track on the loading plate 30.

It is understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection range that all should belong to claim of the present invention with distortion.
